Blue or Gray, Civil War Secret Missions players embark on an unsung career of subterfuge and sabotage, in the role of an 1860s-era commando spy. Presented by History (previously better known as the History Channel), the title follows Activision's earlier Civil War games, continuing in the first-person shooter style of The History Channel: Civil War -- A Nation Divided. Unlike its immediate predecessor, however, Secret Missions favors surgical strikes and guerrilla operations over fast-shooter action and battlefield strategy.
Backed by the broadcasting network, History: Civil War Secret Missions is based on actual recorded events and people from the War Between the States. Players can embark on adventures as members of partisan Confederate cavalry, forward scouts for the U.S. Army, or even handpicked Secret Service operatives, encountering important Civil War figures such as Generals Robert E. Lee, Ulysses S. Grant, and T.J. "Stonewall" Jackson as they go. Missions include railway raids, supply-line strikes, and other low-profile, highly disruptive paramilitary attacks.
